For example, as shown in the figure below, the operation of \"sorting the elements of an array of integer values \u200b\u200bin ascending order\" is alignment.\n\n<image>\n\n\nMany alignment algorithms have been devised, but one of the basic algorithms is bubble sort. As an example, let's arrange an array of given integer values \u200b\u200bin ascending order by bubble sort.\n\n<image>\n\n\n\nIn bubble sort, each calculation step divides the array into \"sorted parts\" and \"unsorted parts\". Initially, the entire array will be the unsorted part.\n\nFrom the beginning of the unsorted part, compare the adjacent elements (green element in the figure) and swap them so that the larger value is to the right. If the two values \u200b\u200bare equal, they will not be exchanged.\n\n<image>\n\n\n\nRepeat this process until the end of the unsorted part (white element in the figure).
